This procedure changes the plan assigned to an organization by
specifying a new plan.

Use this procedure to change the Office Communications Server
Plan assignment from one OCSOrgHosting plan to another. At this
time OCSOrgHosting plans do not contain any features, so there is
no functional difference between OCSOrgHosting plans.

The Hosted Office Communications Server namespace calls
the GetOrganizationPlanAssignment procedure, which will
retrieve the plan assigned to the organization. This validates that
the organization is subscribed to the Office Communications Server
service.

The Hosted Office Communications Server namespace calls
internal private helper GetPlanWithTypeValidation_ for the
specified plan. This will validate that the plan submitted is of
the required type "OCSOrgHosting."
